(warning for vaguely sexual content/fade to black/whatever you want to call it)
This can't be the hardest thing he's ever talked about, but it is definitely up there.
"Well, uh, see, the thing is. The thing is. it has come to, um, my attention that when we have had…sexual relations in the past, I have been the. Um. The one on top."
And it would be better if Feliciano weren't grinning at him, and if he knows where this is goingwhich he does because that is the face he always makes when he knows where this is going he could just step in right about now and save Ludwig a little embarrassment.
But he doesn't.
"And since that does not strike me as, er, particularly fair, I was wondering if you'd like to. . Soon."
He really shouldn't be this embarrassed, either, it's just a question after all, but what if Feliciano thinks it's weird that he wants to—to bottom, or—
"—That sounds wonderful!"
—or that. That could work too.
Feliciano scoots closer to him on the couch. "So do you want to do it now or after dinner or later or what?"
"Y-you don't think it's weird?"
"It's not weird!" Feliciano scoots even closer. "I like it, it feels good, and trying it with you would be great so do you want to try now or later?"
"Now would be all right." Ludwig pecks Feliciano on the cheek quickly, still blushing.
And when Feliciano quite nearly jumps into his lap and starts kissing him, it's not the most difficult thing he's done at all, not by any stretch of the means.
And it does end up being pretty good, too.
